State Machine v0.3.0 Release Notes
Release Date: 2008-09-07 // over 15 years ago-
- No longer allow additional arguments to be passed into event actions
- ➕ Add support for can_#{event}? for checking whether an event can be fired based on the current state of the record
- Don't use callbacks for performing transitions
- 🛠 Fix state machines in subclasses not knowing what states/events/transitions were defined by superclasses
- Replace all before/after_exit/enter/loopback callback hooks and :before/:after options for events with before_transition/after_transition callbacks, e.g.
before_transition :from => 'parked', :do => :lock_doors # was before_exit :parked, :lock_doors after_transition :on => 'ignite', :do => :turn_on_radio # was event :ignite, :after => :turn_on_radio do
- Always save when an event is fired even if it results in a loopback [Jürgen Strobel]
- Ensure initial state callbacks are invoked in the proper order when an event is fired on a new record
- Add before_loopback and after_loopback hooks [Jürgen Strobel]
